Re: Keep 15s or go 17?

I have a set of 16 x 6 ''Wagon Wheel'' rims [other names were White Spoke, Pie Cuts] I bought for my '68 C/10 Stepside in 1999, when the tire shop told me my OEM rims of 17.5x5.25 were shot after about 300,000 miles. I was running R17.5x8LTs. [Also now unobtainable.] [Yes, Seventeen-Five (17.5''). Not a typo.] The backspacing is about 4.'' The right rear was impacted in a collision. I took it into Discount Tires and they checked it out. The rubber tire is OK but there is a slight kink in the rim. It would vibrate at speed, they said. I'm taking that rim to an expert tomorrow, to see if he can true it. A search of local wheel shops and online querries found that 16x6 rims are now obsolete. I can't get a new replacement rim to match the other 3. Hoping the guy can straighten it out, otherwise I'll need to get new rims And maybe tires. Or settle for a different ride height. A friend gave me a set of aluminum rims [take-offs from his '99 4x4 Suburban] and their backspacing is 5.'' I am hopeful they will fit on my '71 K/1500 GMC Jimmy and replace the 33x12.5x15LTs on 15x10 rims. Great meats for off-road, but with gas prices at current levels, their lack of economy is killing me. 16X8 rims with 235/75/16 is the intended replacement. I would not like to use wheel spacers to compensate for modern backspacing. I also have a couple of extra rims from a Nissan. That backspacing is really deep. Maybe 6''. I tried mounting a spare 235/85/R16 on the Stepside from a Toyota [I think] rim -- the inboard clearance is only about 1 finger. The bolt patterns and also hub clearance [for FWD Warn hubs] are OK, but the backspacing is the killer.
